Sanders Industries produced 2,000 tables last month. The standard variable Requirements manufacturing overhead (MOH) rate used by the company is $18 per machine 1. Calculate the variable overhead rate variance. hour. Each table requires 0.2 machine hours. Actual machine hours used last 2. Calculate the variable overhead efficiency variance. month were 370, and the actual variable MOH rate last month was $19.00. Requirement 1. Calculate the variable overhead rate variance. Begin by determining the formula for the variable overhead rate variance, then compute the variable overhead rate variance. (Enter the variance as a positive number. Enter amounts in the formula to the nearest cent and then the final variance amount to the nearest whole dollar. Label the variance as favorable (F) or unfavorable (U).) Options: Actual hours/Actual rate/Actual quantity purchased/Standard hours allowed/Standard rate Variable overhead x rate variance |x Requirement 2. Calculate the variable overhead efficiency variance. Begin by determining the formula for the variable overhead efficiency variance, then compute the variable overhead efficiency variance. (Enter the variance as a positive number. Enter amounts in the formula to the nearest cent and then the final variance amount to the nearest whole dollar. Label the variance as favorable (F) or unfavorable (U).) Options: Actual hours/Actual rate/Actual quantity purchased/Standard hours allowed/Standard rate Variable overhead x ) = efficiency variance x
